一种Android机顶盒USB自动升级实现

A method of Android set top box USB automatic upgrade implementation

为了提高Android机顶盒的改制在工厂中进行升级的效率问题,提出一种USB自动升级的应用实现。在Android机顶盒系统架构中的应用层开发,详细描述了USB自动升级的流程和具体实现方法,并对Recovery模式下安装升级包进行了梳理。相对工厂利用串口升级的传统方法而言具有节省人力、节省时间和节省花费等优点。通过在工厂进行大量升级成功实例,该升级实现具有很好的稳定性、可靠性和很高的升级成功率。

In order to improve the efficiency of Android set top box＇s upgrade efficiency in the factory after initialization , this paper presents anapplication of USB automatic upgrade implementation. Developed in the Android set-top box system architecture＇s application layer , the process of USB automatic upgrade and the specific implementation methods described in detail , sorting to install the upgrade package out in Recovery mode .Compared with the traditional way of using the serial port to upgrade in factory, it has the advantages of saving labor, saving time and cost.Through a large number of successful instances of the upgrade, the USB automatic upgrade achieves good stability, reliability and a high success rate of upgrade.
